Lena Fruman is exercising her Jewish core with fitness balls in the newly renovated Barry and Merle Ginsburg Community Building gym in Vitebsk. This trendy fitness method is mostly yet unknown in Belarus, but these en vogue pensioners are spreading the rage, while firming their abs, with their total-body, low-impact conditioning. Vitebsk seniors aren’t the only ones flexing their muscles with chic workouts. Come to Minsk, where Hesed Rachamim’s golden-agers attend dance and pilates classes in the Minsk Jewish Campus. So for those optimum abs, buns, and thighs, it’s best to keep with the Jewish Belarusian Babushkas, who stay on the move with the latest fitness trends.
